IMPROVEMENT IN noon-BUTTONS.

The Schedule referred to in. these Letters Patent and making part of the name.

To all whom it may concern:

Beit known that we, THOMAS LINCOLN and GEORGE HUBBARD, ofNew Haven, in the county of New Haven, and State of Connecticut, have invented a new Improvement in Door-Button; and we do hereby declare the following, -when taken in connection with the aecompanying drawings, and the letters of reference marked thereon, to be a full, clear, and exact description of the same, and which said drawings constitute part of this specification, and represent, in-

Figure 1, a top view; Figure 2, the same, with the button turned;

.Figure 3, an under-side view of the turn-button;

Iigure 4, a top view of the plate, with the button ren-oved; and in' 1l igure 5, arsectional view, between the plate and button, looking toward the button.

This invention relates to an improvement in the article of manufacture known to the trade as door, or turn-buttons, the object being ,to provide the button with a mechanism which shall automatically turn the button to right angles, or nearly so, when the button has been partially turned toward such angle; and

`The invention consists in forming, upon the plate, a. square boss, and a recess, within the button, settingover the said square boss, and with springs litted into 1 the recess in the button,and bearing upon the said boss, so Athat the natural place of rest is upon one of the sides of the boss, and so that when the button is.

turned to caxry the spring over one of the angles, lthe reaction of the spring will'force the button over, so as to carry th spring on to the dat surface of the boss.

To enable others to fully understand our invention, we will describe the same, as illustrated in the accompanying drawings.

A is the plate, formed with a square boss, a, or with a projection, having one or more dat surfaces, B.

The turn-button is provided with a recess, C, on its under side, so as to set on over the bo'ss; and through a central perforation in the button, and through the boss, a rivet, d, is placed, to secure the two parts together, and form a pivot, upon which the button turns.

The recess in the button is suiiciently broad to permit the button to turn freely around the boss a and in the said recess, upon one or both sides, we place a spring, f, (see fig. 5,) the tendency of which is to retain the button with the springs lying upon the flat side of the boss. Therefore, when the button is partially turned, so as to remove the springs from the flat surface, the said springs will, of their own'inclination, carry the button around, so that the springs will rest upon the nearest flat surface,-whether it be in the po' sition seen in fig. 1 or fig. 2.

We do not wish to be understood as broadly claiming the construction of a turn-button, so that it will be held in any given position, as such, we are aware,i

is not new; but v What we doelaim as new and useful, and desire to secure by Letters Patent, is

The button B, provided with the recess O, and cornbined with the plate A, constructed with the boss a,

V and itted with one or more springs, f, so as to operate substantially in the manner specified.
